ADJUSTABLE JOURNAL-BOX.

Specification of LettersPatent.

Patented Mar. 13, 1917.

Application filed April 5, 1916. Serial No. 89,088.

To aZZ whom it may concem; Be it known that 1,-JAMES C. THERIOT, a

citizen of the United States, residing at Taft, in the county of Kern and State'of California, have invented certain new and useful, Improvements in Adjustable J ournal-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to improvements in adjustable journal boxes, and has for its pri- -mary object to provide simple and efficient means for effecting an accurate adjustment of the relatively movable bearing piece of a journal box.

Another object is the provision of a novel adjusting device for journal boxesof the type described and claimed in my pending application Serial No. 81,952, filed March 3, 11916, embodying a single wedge or taper l Vith these and other objects in view, the invention consists in the novel construction; combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which: Figure 1 represents a fragmental side elevation, partly in section, of a well known type of journal box, illustrating .the improved adjusting device applied thereto,

Fig. 2 represents a side elevation,of the improved adjusting device removed,

Fig. 3 represents an edge elevation, partly in section, V j

Fig. 4 represents a fragmentary side elevation, partly in section, of a journal box, illustrating a modified type of the adjusting means applied thereto, r

Fig. 5 represents a side elevation of the modified type of adjusting device removed, and

Fig/6 represents a longitudinal sectional view on the line 66 of Fig. 5.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 7 indicates a shank, preferably rectangular in cross section and provided with a pair of spaced lateral projections 8,- arranged at and adjacent one end ofthe shank 7. The end of the shank opposite the projections 8 is rounded,

as indicated at 9, and formed with external screw threads.

A wedge or taper key 10 is arranged with one ofthe faces thereof in sliding en agement with the side face of the shank 7 opposite the projections 8, and the relatively large end of the wedge is reduced in width and directed angularly, as indicated at 11.

The-recess 12 between the angular end 11 and the shoulder 13 receives a nut 14,thread-,

ed upon the shank 9. The angular end 11 is formed with an opening15 of such diameter as to slidably receive the screw threaded terminal 9 of the shank and permit-longitudinal adjustment of the wedge .10 with relation thereto. An adjusting nut 16 is fitted upon the screw threaded terminal 9 of the shank and is engaged with the side of the angular end 11 of the wedge opposite the nut 14, and adapted to co-act therewith to lock the wedge in adjusted position with relation to the shank 7 A lock nut 17 is The adjusting device above described is particularly designed for use in connection with a connecting rod journal box of the 1 type illustrated in Fig. 1, and which includes the connecting rod 18, U-shaped strap19 rigidly connected with the head S engaging the. parallel members of the U-shaped strap and securing the shank in position. The wedge 10 is engaged with the relatively adjustable bearing piece 21 and isadapted to be moved longitudinally of the shank 7 by properly adjusting the several nuts 14, 16 and 17 to effect the desired adjustment of the bearing piece 21 with relation to the bearing piece 20.

Referring to the modification of the invention illustrated in Figs. 4 to 6, the numeral 25 indicates the shank of the adjusting device which is preferably rectangular in cross section and provided at one end with a cylindrical head 26. The. portion of the shank 25 opposite the head 26 is rounded and formed with external screw threads 26 on which is fitted an internally screw threaded nut or clamping plate 27,

adapted to co-act with the head 26 in securing the shank position in the journal box.

A wedge or taper key 28 is engaged with one side face .of the rectangularshank-25 and the clamping plate 27and the relatiyely large end thereof is reduced in width, directed angularly and 'apertured, as indicated at 29, to slidably receive the screw threaded portion 26 of the shank. Adjusting nuts 30 and 31 are fitted upon the screw threaded portion of the shank and are engaged with the opposite sides of theangularly directed portion 29 of the wedge 28 to eifect the desired adjustment of the latter with relation to the shank 25. A look nut 32 is fitted upon the shank 25 and is engaged 1 with the outer adjusting nut 30 for locking the latter in adjusted position.

Inapplying thev type of adjusting device illustrated in Figs. 4, 5 and 6 to a journal box, the shank 25 is inserted through the slots 22 in the strap 19 and is secured in position by adjusting the plate .or nut 27, so as'to draw the latter and the head 26 in j firm engagement with the parallel portions of the strap 19 The wedge 28 is subsequently adjusted by means of the several nuts 30, 31 and 32, so as to effect the desired adjustment of the relatively adjustable bearing piece 21 with relation to the stationary bearing piece 20*. v

WVhat I claim is:

1. In an adjustable journal box, a shank having one end screw threaded, a wedge slidably engaged with said shank and having an angular apertured end slidably receiving the screw threaded portion of said shank and arecess adjacent the angular end, and adjusting nuts fitted on the screw threaded terminal of said shank and engaged on the opposite sides of the angular terminal of said wedge and one of said nuts being confined between one side wall .of the recess and the angular terminal of said wedge, said nuts constituting adjustable means f-or rigidly. securingthe wedge against longitudinal movement in, either dlI'GCtlOIl llPOn the shank.

2. In an ad ustabie journal box, a shank having one end screw threaded, ahead at the opposite end of said shank, a clamping plate adjustablyfitted on the threaded end of said shank, a wedge slidably engaged with said shank having. an angular aper-- "shank.

In testimony whereof I afiix my signature in presence of two witnesses.
